Abstract
The utility model relates to the friction device technical field, especially relates to the improved friction device for the scroll machine, which comprises a driven roller cylinder main shaft and a supporting seat mounted on the main shaft, characterized in that, one end of the main shaft is connected with a friction disk, a friction base and a pressure spring after passing through the supporting base, the main shaft end after passing through the pressure spring and a pressure regulating nut are in the screw connection, the friction disk and the supporting base are in the tight contact to form the pressing and matching contact face; compared to the prior art, the utility model has novel and simple structure, as a result that a pre-tightening buffering friction device is provided on the driven roller cylinder, accordingly, the resistance force of the driven roller cylinder can be increased, thereby effectively preventing the rotating of the driven roller cylinder because of the forward inertia, ensuring the scroll to be in the tightened state all the time no matter during operating or stopping, ensuring the scroll not to be creping, and greatly improving the production efficiency, without folded corners and fringes, and the pre-tightening buffering friction device has advantages of low producing cost, reliable performance and environmental protection, the energy resources can be saved, and the utility model is worth popularizing and applying.
Description
[technical field]
The utility model relates to the strigil technical field, specifically a kind of modified scroll machine strigil.
[background technology]
In the market, the use of scroll machine is more and more frequent, and its operation principle is also similar substantially.Vertically hung scroll cloth twists on active roll tube and the passive roller, and when active roll tube rotated, active roll tube just drove passive roller and rotates together, thereby carries out work.Yet when the active roll tube of scroll machine stops operating, passive roller is because inertia, can continue to turn an angle forward, thereby cause vertically hung scroll cloth relaxation to occur, defective such as make that the print content on the vertically hung scroll cloth is wrinkling, knuckle, striped, print content are crooked.Address this problem in order to eliminate such defective, to press for.
[utility model content]
The purpose of this utility model is exactly will solve above-mentioned deficiency and a kind of modified scroll machine strigil is provided.Passive roller also continues to rotate forward owing to inertia after having prevented the scroll machine active roll tube to stop operating effectively.
Design a kind of modified scroll machine strigil for achieving the above object, comprise passive roller main shaft and be installed in supporting seat on the main shaft, described main shaft one end passes behind the supporting seat cross-under friction plate, friction seat and stage clip successively, pass spindle nose behind the stage clip look nut that is threaded, closely contact between described friction plate and the supporting seat and form the contact-making surface of compression fit.
The contact-making surface that described supporting seat and friction plate form compression fit is a rubbing surface.
Described friction plate is made integrative-structure with the friction seat.
The utility model is compared with prior art, novel structure, simple, because passive roller is provided with and is with pre-locking buffering strigil, increased the resistance of passive roller, thereby can prevent passive roller effectively because inertia rotates forward, no matter guaranteed that scroll machine is in running or halted state, vertically hung scroll remains tight state, guarantees wrinkle resistant, the no knuckle of vertically hung scroll content, no striped, has greatly improved production efficiency, and, this pre-locking buffering strigil cost of manufacture is low, dependable performance, environmental protection, save a large amount of energy, be worthy of popularization.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 is that supporting seat, 2 is that friction plate, 3 is that friction seat, 4 is that stage clip, 5 is that look nut, 6 is a main shaft.
[specific embodiment]
Further specify below below in conjunction with accompanying drawing the utility model being done:
As shown in Figure 1, the utility model comprises passive roller main shaft 6 and is installed in supporting seat 1 on the main shaft, described main shaft one end passes behind the supporting seat cross-under friction plate 2, friction seat 3 and stage clip 4 successively, pass spindle nose behind the stage clip look nut 5 that is threaded, closely contact between described friction plate and the supporting seat and form the contact-making surface of compression fit, the contact-making surface of described supporting seat and friction plate formation compression fit is a rubbing surface.
In addition, friction plate of the present utility model can also be made integrative-structure with the friction seat.
Design principle of the present utility model: owing to closely contact between friction plate and the supporting seat, thereby between have certain coefficient of friction, make main shaft at the certain resistance of Shi Junyou that still stops operating that turns round, passive roller also continues to rotate forward owing to inertia so just can to have prevented the scroll machine active roll tube to stop operating afterwards effectively.The design of stage clip and look nut is for the ease of regulating the frictional force between friction plate and the supporting seat.
Claims (3)
